Specification of Letters Patent. Pat t d D 2 1926' Applioation'nled November 16, 1917. Serial No. 202,310.

To all whom it may concern:

Be-it known that we, Crmnnns E. Wrnson, a citizen of the United States, and a resident of Wilkins township, in the county cf -Alle'gheny and State of Pennsylvanimand Lnsnm O. PAi nn a citizen of the United States, and aresident of Swissvale, in the machines and particularly to certain struc.

tural features of generators for use on. automobiles or other vehicles for supplying current to batteries, lights, and other devices.

The object of our invention is to provide an end-bracket structure for-such a generator on which mechanisms may be conveniently arranged and mounted so as to be fully protected from injury and still be accessible I for inspection, adjustment and repair.

The above and other objects and the novel features of the invention willbe apparent from the following description, taken in connection with the accompanying drawings which constitute a pa Of his application and in which Fi re 1 18 9, View, mainly in longitudinal section butparti flly in side ele, vation, of a generator embodying-the invention. Fig. 2 is a view, in end elevation, of

a generator embodying the invention, showing the improved .end bracket for supporting ignition and controlling mechanisms, the

cover of the regulator and cutout compartment being omitted. Fig. 3 IS a sectlonal tion for the structure that lends itself to cradle mounting on the engine. The bracket 8 has a central opening therein containing an anti-friction bearing 10 for the armature shaft 7 that projects through said bearing.

.Th'eend bracket 9. at the commutator end of the machine embodies the "features of the present inyention and has a cylindrical flange portion 11 that surrounds the commututor cylinder 5 and the brushes 6 and is proor wall 13 within the flange 11 that is proview of another generator embodying our invention, and Fig. 4 is an end view of the generator shown in Fig. 3, the cox er of the regulator and cutout compartments being removed.

The dynamo-electric machine comprises a cylindrical frame or yoke member 1, pole pieces 2 that are bolted to the inner surface of the yoke member and are surrounded by field coils 3, an armature 4, a commutator cylinder 5, brushes 6, and a shaft 7 upon which the armature and commutator cylinder are mounted. Circular end brackets 8 and 9 are attached to, and close the ends of, the cylindrical field frame or yoke 1, the

bracketsbeing'disposed within the marginal outline of the yoke to provide a circular secvided with a. central opening 14 through which the shaft extends into a compartment 71 outside of the wall'1-3. A rocker ring 15, that carries holders 16 for the brushes 6, is attached to the inner side of the wall 13. Y

The outer end. face of the bracketQ is provided with walls that farm a completely inclosed compartment 18 with the wall 13 and the cover 19. The compartment 18 contains current controlling mechanism connected in circuit with the generator, said mechanism comprising a regulator 20 for the field excitation of the generator and a cutout switch 21 for controlling the connections of the generator to the external circuit in accordance with the generator voltage. ,The connecting leads of the regulatorand cutout switch to the generator pass through openings 22 and 23 in the wall 13.

The regulator 20 is described in Patent No. 1,180,039 and is also described more specifically in another application, Serial No. 200,663 filed Nov 7, 1917, that has also been assigned to the 'iVestinghouse Electri & Manufacturing Company. Inasmuch as ihe present invention does not appertain to the 26 tending to separate the armature from the central leg 23, a contact member 27 car- .ried by the armature, a cooperating contact incense armature shaft which has a portion thereof exposed in said compartment, a cam upon the exposed portion of the armature shaft, and current-regulating means in said com- .partment, and actuated by said cam, said mature structures; and an end bracket atwvall that closes one 81H.

tached to said frame Within the margin of the latter and having a compartment, bracket comprising a wali that closes one end of the frame and has a part constituting one side of said compartmeiu'j a cover for said compartment, said wall having a bearing support for one end of the armature shaft, and a current regulator in said compartment connected in circuit with said generator "by conductors passing through said Wall, said compartment having a separate opening for permitting the adjustment of the regulator without removing said cover.

5. A dynamo-electric machine compris; lg a cylindrical frame containing the fieldmagnet and armature structuies a circular end bracket attached to said frame and comprising a Wall that closes one end of the frame, a compartment formed outside said frame, and independently acting currentcontrolling devices located in said compartment for controlling said dynamo-electric machine and mounted on one side of said iyall.
